JSF UI Framework

URLs for Files

File URLs within JSF Context Only

The default URL patterns for downloading files from within the JSF environment are:

  • http://NUXEO_SERVER/nuxeo/nxfile/{repository}/{uuid}/blobholder:{blobIndex}/{fileName}
  • http://NUXEO_SERVER/nuxeo/nxfile/{repository}/{uuid}/{propertyXPath}/{fileName}

Where:

  • nxfile is the download servlet. Note that nxbigfile is also accepted for compatibility with older versions.
  • repository is the identifier of the target repository.
  • uuid is the uuid of the target document.
  • blobIndex is the index of the Blob inside the BlobHolder adapter corresponding to the target Document Type,starting at 0: blobholder:0blobholder:1.
  • propertyXPath is the xPath of the target Blob property inside the target document. For instance: file:contentfiles:files/0/file.
  • fileName is the name of the file as it should be downloaded. This information is optional and is actually not used to do the resolution.
  • ?inline=true is an optional parameter to force the download to be made with Content-Disposition: inline. This means that the content will be displayed in the browser (if possible) instead of being downloaded.

Here are some examples:

  • The main file of the document: http://NUXEO_SERVER/nuxeo/nxfile/default/776c8640-7f19-4cf3-b4ff-546ea1d3d496
  • The main file of the document with a different name: http://NUXEO_SERVER/nuxeo/nxfile/default/776c8640-7f19-4cf3-b4ff-546ea1d3d496/blobholder:0/mydocument.pdf
  • An attached file of the document: http://NUXEO_SERVER/nuxeo/nxfile/default/776c8640-7f19-4cf3-b4ff-546ea1d3d496/blobholder:1
  • A file stored in the given property: http://NUXEO_SERVER/nuxeo/nxfile/default/776c8640-7f19-4cf3-b4ff-546ea1d3d496/myschema:content
  • A file stored in the given complex property, downloaded with a specific filename: http://NUXEO_SERVER/nuxeo/nxfile/default/776c8640-7f19-4cf3-b4ff-546ea1d3d496/files:files/0/file/myimage.png
  • The main file of the document inside the browser instead of being downloaded:  http://NUXEO_SERVER/nuxeo/nxfile/default/776c8640-7f19-4cf3-b4ff-546ea1d3d496?inline=true

For Picture document type, a similar system is available to be able to get the attachments depending on the view name:

  • http://NUXEO_SERVER/nuxeo/nxpicsfile/{repository}/{uuid}/{viewName}:content/{fileName}

where, by default, viewName can be Original, OriginalJpeg, Medium, Thumbnail.

Producing File URLs from JSF Templates

For a single file, in schema "file", where blob field is named "file" and file name field is named "filename":

<nxh:outputLink
  value="#{nxd:fileUrl('downloadFile', currentDocument, field.fullName, currentDocument.file.filename)}">
  <nxh:graphicImage
    value="#{nxd:fileIconPath(currentDocument[field.schemaName][field.fieldName])}"
    rendered="#{! empty nxd:fileIconPath(currentDocument[field.schemaName][field.fieldName])}" />
  <nxh:outputText value="#{currentDocument.file.filename}" />
</nxh:outputLink>

For a list of files, in schema "files", where list name is "files" and in each item, blob field is named "file" and file name field is named "filename":

<nxu:inputList value="#{currentDocument.files.files}" model="model"
rendered="#{not empty currentDocument.files.files}">
  <nxh:outputLink
    value="#{nxd:complexFileUrl('downloadFile', currentDocument, 'files:files', model.rowIndex, 'file', currentDocument.files.files[model.rowIndex].filename)}">
    <nxh:graphicImage
      value="#{nxd:fileIconPath(currentDocument.files.files[model.rowIndex].file)}"
      rendered="#{! empty nxd:fileIconPath(currentDocument.files.files[model.rowIndex].file)}" />
    <nxh:outputText value="#{currentDocument.files.files[model.rowIndex].filename}" />
  </nxh:outputLink>
  <t:htmlTag value="br" />
</nxu:inputList>

This gives you the URLs of the form:

http://NUXEO_SERVER/nuxeo/nxfile/default/8f5aca13-e9d9-4b7b-a1d9-a1dcd74cc709/blobholder:0/mainfile.jpg
http://NUXEO_SERVER/nuxeo/nxfile/default/47ad14f2-c7a6-4a3f-8e4b-6c2cf1458f5a/files:files/0/file/firstfile.jpg
